A. FBSSENDEN. RECEIVER FOR ELEGTROMAGNBTIU WAVES. .PPLIUATIOH FILEDPBLZ, 1906.

Patente@ may 11, 1909 small electrode, an absorbent material chargedwlth an electrolyte 1n contact with the electrode reslhently underpressure, and

to the other to vary the pressure.

5. A receiver having in combination a dia- I phragm, a small electrodeconnected to the 4means for'adjusting one of said parts relative v 1smoved by change of the pressure of the diaphragm, an electrolyte incontact with the electrode, lsaid parts being so arranged that thepressure ot' the electrolyte on the electrode is varied by receivedoscillations and motion 1s imparted to the diaphragm.

6. A receiver l'or electro-magnetlc waves'v comprising an electrode, amedium containing an electrolyte and having a resistance,

and means l'or maintaining a yielding pressure between said medium andelectrode.

7. A receiver l'or electro-magnetic waves comprising a resisting mediumcontaining au electrolyte, and an electrode held in contact therewithunder a yielding pressure.

S. A receiver l'or electro-magnetic waves comprising a medium capableolI resisting pressure and containing an electrolyte, a movableelectrode in contact with the electrolyte underpressure, and a sounddia-I phragm connected to the electrode, substantlally as and l`or thepurpose described.

9. A receiver for signalin comprising a stationary body of uld, anan"indicatm device mechanically connected to said 'ltuit iunderpressure, so that the indicating device lluid against the electrodecaused by electical impulses received.

l0. A receiver comprising a fluid, a terminal in contact with the fluidso as to be niechanically moved by change of ressure of the. contactcaused by electrica impulses,

4and an indicating device connected to said terminal.

ll. A receiver comprising a stationary body ol'lelectrolyte, anelectrode in contact. therewith under resilient )1'essure,`and anindicating device connected and adapted to be moved by chan e of volumeol' the electrolyte, substantialy as de.- scribed.

In testimony whereof, l have hereunto set my hand and seal, the 18th dayol' April l). lllllti.
